(54) Pantograph


(57) A pantograph for an electric-driven vehicle includes frame (1) electrically insulated from the vehicle where on eccentric shaft (3) girder (4) is mounted pendulously and the said girder is connected by means of an articulated joint with at least upper arm (6) equipped with the slide unit coupled with it. The pantograph is equipped with electric lifting drive (13) electrically insulated from the vehicle and from girder (4) and equipped with at least one tension spring (18) coupled with girder (4).
By means of electric insulator (15) and double-arm drive lever (17) mounted pendulously in frame (1), drive (13) is coupled with one end of the tension string (18), whereas the other end of spring (18) is coupled with girder (4), preferably by a non-circular return strand transmission with open strand (23) whose axis of rotation corresponds to the axis of rotation of girder (4) in relation to frame (1).
